PURPOSE:To prevent toner from leakage by forming opening parts to be connected to each other on an inner cylinder and an outer cylinder which are fitted with each other so as to be relatively rotated and fixing a sealing member for sealing the opening of said inner cylinder to a gap between the inner and outer cylinders. CONSTITUTION:In the powdery particle case, the inner cylinder 1 consisting of a cylindrical iron can of which both the ends are closed is fitted with the outer cylinder 2 consisting of a cylindrical iron can of which one end is opened and an opening part 4 divided into two parts at a cut residual part 3 on the center is formed on the peripheral wall of the inner cylinder 1. Both the end edges of the flexible sealing member 9 are fixed on the outside of the inner cylinder 1 adjacent to the opening part 4, the outside of the inner cylinder 1 adjacent to the opening part 5 and the inside of the outer cylinder 2 adjacent to the opening part 5 respectively with double-sided tapes or the like. Said constitution makes it possible to prevent the toner from leakage. |
